Almost done installing Vape on my 77 TD400 . Had to remove material from pick up and side cover to enable cover to sit flush. I set  static timing (with Supertunres notes) with relationship of pick up to rotor. I have verified voltage is good and ignition relay operating.  Now need to add pointer and mark rotor to verify timing with my old Craftsman timing light. If timing is off, I want between 1.8 and 2.0 btc can I adjust by moving pickup  side to side ? Clearance is almost 0 to cover. or do i have pull rotor and reset on crank?

Whats the best way to remove 43 year old decals from the plastic side covers ? Just ordered new decals just doing side covers leaving tank alone its original stickers and paint pretty good. I also bought rattle can of original Chappy red to repaint covers.
Thanks in advance 

Does anyone have any info, pics or specs on how to do stinger and silencer modification on RD400 DG chambers ?. The old site had some info that I think was done by Coolhead using 3/4'' emt and reusing DG silencer with mods to that.
The DG's exhaust outlet stock is 1 1/8''.
It also said the stinger most be smaller than perf tube. Just purchased a flux welder to fix lawn mower, DG's next.
Anyone else done it?

 I ran Yamalube R for about 1000 miles on new ProX pistons and rings. I and found about 0.001 wear on pistons and ring end was huge gap . I called Yamaha and they say only to use Yamalube R for premix and run Yamalube S for injection. I just had cylinders honed and installing new pistons and rings did leak down test held 6 psig for over 1/2 hour.  Any suggestions on oil  choice would be appreciated.

 Wow, What a relief to have this  forum back to tap into all the info and experience out the to help each other.
My question is I  just bought the Boyesen 2 stage power reeds from John  Economy Cycle, Do I remove the factory reed stops and use the provided "rev-plate" or keep the factory stops.?
